Example Embodiment

[0022] Reference below figure 1 versus figure 2 The present invention will be further described in detail through specific embodiments.

[0023] First, fix a set of vise on the machine tool to level the vise horizontal positioning surface, align the vise fixing jaw 5, and use the bolt to press the vise chassis to position it with the machine tool; and to the left of the outermost vise on the left A longitudinal reference positioning block 10 is added to the side to position the parts longitudinally, and then the deformable double-sided cavity rectangular long rod with milled six-sided thick reference is positioned and tightened in this group of vices. Press the pressure plate from left to right to flatten and press the parts, so that the bottom surface of the part and the horizontal positioning surface of the vise completely fit; the clamping force of the vise's live jaw makes one side 7 of the part completely fit the fixed jaw 5 of the vise Clamp the part completely. Cut the ...

Abstract

Provided is a machining method for a proteiform double-side-cavity square long rod part. In the cutting machining process of the proteiform double-side-cavity square long rod part, the external constraint in the machining process of the proteiform double-side-cavity square long rod part to be machined is supplemented by making the outline of the proteiform double-side-cavity square long rod part to be completely attached to the outline of a vice fixed jaw used for a clamping machine. A first side cavity is subjected to rough machining to be once cut deep to a size, and a second side cavity is subjected to rough machining through clamping positioning with a combined vice, flattening a workpiece with a pressing plate and clamping the part with a vice, so that the principle that stress exerting on the two sides of the proteiform double-side-cavity square long rod part is even and counteract each other is guaranteed; the defect that the proteiform double-side-cavity square long rod part can not be machined due to bending deformation in the cutting machining process of an inner cavity of the proteiform double-side-cavity square long rod part is overcome; the product machining efficiency and the qualification rate of the proteiform double-side-cavity square long rod part are improved.

Description

technical field [0001] The invention relates to the technical field of cutting processing of deformable square long rod parts, in particular to the technical field of inner cavity cutting processing of deformable square long rod thin-walled parts. [0002] purpose of the invention [0003] It overcomes the defects of high processing strength, low processing efficiency, and unguaranteed part size due to deformation and bending of easily deformable square long rod parts during the cutting process of the inner cavity, and improves the processing of easily deformable square long rod parts. Efficiency and product qualification rate. Background technique [0004] Usually, the processing method of easily deformable parts in double-sided cavity, especially forgings, is to process in layers of 1-2mm in the inner cavity of the part, and after each layer of one side is processed, the part needs to be turned 180 degrees to process the other side, repeated many times Flipping and layer...
